Attman's Deli, resident of Corned Beef Row in Baltimore since 1915 (see the Roadfood.com review), is opening a second location next year, in Potomac, MD, northwest of Washington D.C. On December 3rd they tweeted "146 days to go" so, if our math is correct, they're shooting for an end-of-April opening. They will be located in the Cabin John Shopping Center at 11325 Seven Locks Road.
